To all whom/ may concern.'

Be 1t known that I, JAMES SNEDDEN, a

citizen of the United States, residing at' Wichita, in the'count of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Hydrocarbon- Burning Furnaces, of which the following is a specification.

My invention relates to certain improvements in the construction and operation of fuel oil or hydro-carbon burners as applied to furnaces or steam boilers and heaters of every description.

Generally stated, itv consists of an air compressor or blower suitably operated in conjunction with an oil pump to supply the requisite amount of air and oil for combustion. and the essentiiil features of my invention are more fully shown in the accompanying drawings, w ere- Figure `l is an elevation of one embodiment of my device, representing an ordinary hot water heating plant; Fig. 2 a vertical section of Fig. 1; Fig. 3 is an elevation in lsmaller scale of the motor. air compressor and pump; and Fig.y 4 is a detail View in larger scale of the regulating valve.

A is the motor and B the air compressor; (l is the oil pump arranged to operate in unison and D the air pipeleading to the tank ll. I.

E are. the pipes for'heating the air in its passage to the burners P.

I*` is the oil pipe and coils for heating the oil in its passage from the pump to the hurners or burner. The coils F3 are shown in Fig. 2 at the top of an ordinary hot Water healing planl luft may be located anywhere convenient .but .t'ar enough away' to heat but not burn the oil in its passage through the coils en rol/jc to the burners. It will be seen that the`air pipe E the furnace or firebox, so that the air in its imssage through' it, is heated to such a de'- gree that. when the ail and oil unite at the burner. they readily ignite, that being the ideal condition essential to perfect combustion.

(l (see Figs. l, 2 and 4) is the regulating valve for controlling the amount of the mixture requisite to different degrees of heat. The valves M andO on the connections Ell and F,'between the valve G and the pipes E and F respectively serveas a cuto and when proper amount of air and is placed in the side of y l said burner from oil has been sure is controlled by the regulator or pop N on the tank H. This at all times secures a uniform pressure for the air, and owing to I the pbjectiOn, on part of insurance companies to all forms of gravity feeds for the oil., I,in practice, place the oil tank or reservoir underground and preferably lift'the oil' and force it through the coils F at such a pressure as will insure its reaching the burners unilnpaired by the heat in the coils. By means of an overflow pipe F2, the sur# plus oil isfreturnedsto the reservoir, it being my object to avoid any accumulation of oil near t-he furnace which might prove ace or fruitful lsource of fire. There is like? wise an air return pipe E2. pressor pump is run by a belt B? from the motor A and the'oil pump C is in turn operated by a belt C1 from the compressor shaft, so that in case the motor Vshould fail, the air and oil pressure would fall and the fire go out. It will benoted that airand oil, though heated in separate coils. do not unite until they reach 'the burners or where they are ignited within the furnace proper. and I so proportion my air and oil pipes. that it will. only valves M and O, and that by merely opening oil is at all times assured independent of any form of regulating valve or mixer.

I claim rj l. In a hydrocarbon burning "furnace, having a combustionfchambenin combination a source of compressed air supply, a source of liquid fuel supply, .al burner in said chamber, and individual. `'conduits to said burner from said sourcesof air and fuel supply; 'said compressed airconduitA comprising a coiled pipe in the path" of the flame within the combustionchamber; said liquid fuel conduit comprising aciled pipe iulthe 'combustion chamber f-andremoved from the tlame, to a desired temperature.

In a hydrocarbon burning furnace, having a combustionchamber, in combination a source ofcompressed air supply, a source of liquid fuel said chamber, and indivi supply; said,JV compressed air conduit com- Patented May 27. 1 m

be necessary to use the supply, a burner in' ual conduits to saidsourees of air and fuel them full. the requisite amount of air and l whereby thefuel is heated prising a coiled pipe in the path of the ame within the combustion chamber; said liquid fuel conduit com rising a coiled pipe in the combustion cham er and removed from the flame, whereby the fuel is heated to a desired temperature; an inlet Valve on said burner controllin the admission of both air and fuel to 'said burner, and individual valves in seid conduits, whereby the relafive quantity of air and fuel will be adjusted in 10 the combustion mixture admitted to the burner through said inlet Valve.
